Sorry for the typo. Unlike languages like Java functions are first class citizens In Scala.

It means functions are first class citizens I like languages like Java.

Thanks. Are these 2 things not the same. As Scala has functional features from the word “go”,  so it requires us to write less code as compared to say Java for this reason.

The primary advantage of using Scala is that in Scala we need to write lesser code. For example to achieve the same result as in Java, we require to write lesser code. Is this advantage only due to the reason that in Scala functions are first class citizens unlike say Java.  

Thanks.

Thanks. So there is no automatic retry for attempting connection unless we explicitly code for that in the catch block.

Example. If a database gives 30 concurrent connections and code runs multiple times for thousands of records the  running out of connections will eventually happen.

So once it send the exception does it retry automatically when connection is available or that code never executes at all?

No closing connections properly can lead to running out of connections. That means that it can become a reason for applications to run slowly.    Although it is different from original question what happens when a code tries to get connection but max number of connections available are already occupied. Does this code never run or it waits and then runs when it gets the connection ?

Does not closing connections properly is also a reason that can make the program slow?

I think in case of spark, It can a spark word count program and one can add small functionalities to that for further practice.

If the code has too many read operations does it become slow because of that?

Hadoop is not mandatory for running Apache Spark programs. However if I am running spark word count sample application  from Eclipse it gives error and works only when I set Hadoop home to the path of folder containing Winutils.exe. Why is it required when Hadoop is not mandatory for Spark?

Thanks.  In doing this instead I got a window which has properties written on it and has advanced and Misc tabs
Different programming languages are suitable for different things. Like C is suitable for OS coding, game programming etc,  Pyhthon is suitable for data science, artificial intelligence etc. Thus I thought someone already knowing scala could guide me that which types of examples I can focus on to start with.

Eclipse has a short cut control O which can be used to see all the methods quickly? Does Visual Studio has any such shortcut?

Thanks
